Quick answers
- Is the 3.5" HDD Tray in stock right now?
- Yes. At NotiFi's most recent check of the official US UniFi store, at least one 3.5" HDD Tray variant was purchasable. Popular gear can sell through quickly, so if you need it, order sooner rather than later.
- How often does the 3.5" HDD Tray restock?
- NotiFi observed 5 restocks in the last 90 days, with sold-out gaps averaging about 6 days. Past cadence is not a promise, but it is the best available signal.
- How long does the 3.5" HDD Tray stay in stock?
- The median in-stock window over the last 90 days was about 17 hours. Short windows are exactly why an alert beats manual checking.
- How do I get notified when the 3.5" HDD Tray is back in stock?
- Watch it in NotiFi, the UniFi stock alert app for iPhone. NotiFi checks every product and variant on the official store continuously and pushes within minutes of stock flipping; Ultra plans can also forward alerts to Discord, Slack, or Home Assistant via webhooks.
The 3.5" HDD Tray is purchasable right now. Before you commit, two things worth reading: Sold Out vs Coming Soon: store labels explained and UniFi store vs resellers.
